There are several of the ranchers that build and sell "holding" cages/runs that usually come in sets of 3 to 5 attached together ... similar to runs, but without the male run in the back.
Ralph Shoots makes them ... He has made over 40 for us already. We usually pick them up at a show we are both going to be at, but he also ships them. Very good quality and at a good price.
He's listed on the Empress and M.C.B.A. websites under ranchers. His chins are also georgous!
